[libgo, build] Avoid echo -n in gotest

[Rainer Orth]

Inspecting the Solaris 8 libgo.sum file, I was reminded that echo -n
isn't portable.  The autoconf manual agrees and suggests printf as a
replacement.  The following patch implements this.

Bootstrapped on i386-pc-solaris2.8 with gas.

	* testsuite/gotest: Use printf instead of echo -n.
